Description
Summary:Background: Obesity has become a global issue, since there are numerous indications that a greater number of children and adolescents are becoming overweight each year. In Greece, increasing trends in the proportion of overweight children have been observed. Nonetheless, epidemiological information is lacking as these findings pertained to different population samples, and robust conclusions could not be drawn. Aim: The purposes of the present study were to assess the body mass index (BMI) and prevalence of overweight and obesity in a population-based, representative sample of Greek children at the ages of 7 and 18, and to examine changes in the proportion of children classified as overweight or obese from childhood to adolescence. In addition, we examined the association between BMI z-score at 7 and 18 years, and change in BMI z-score from 7 to 18 years, and perinatal, child, parental, socio-economic and adolescent lifestyle characteristics. Finally, cross-national comparisons aimed to reveal similarities and differences in the weight status of children and adolescents, and in characteristics among adolescents of a Northern (Finland) and Southern (Greece) European country. Population and methods: A total of 11048 neonates, that represented 8% of the country’s annual births, were recorded nationwide from the 1st to the 30th of April 1983 and constituted a representative, population-based sample. Children were followed up through two, separate, questionnaire surveys conducted in 1990 and 2001. The first follow-up survey was conducted through primary schools nationwide, whereby a total of 8130 completed questionnaires from 7-year-olds nationwide were returned, and 6143 were merged with corresponding data from the 1983 survey. During the second follow-up participants were located at high-schools throughout the country. Of the 4675 questionnaires distributed, 3500 responded (75% response rate). For each survey, the questionnaires were kept anonymous. Finally, data was matched-up through the three study periods using ...
